Soit M 0 une variété riemannienne complète à courbure de Ricci bornée inférieurement et qui vérifie l’inégalité Sobolev de dimension ν>3. Si M est une variété riemannienne complète isométrique à M 0 en dehors d’un compact et si p(ν/(ν-1),ν) alors lorsque la transformée de Riesz est bornée sur L p (M 0 ) elle est également bornée sur L p (M).

Assume that M 0 is a complete Riemannian manifold with Ricci curvature bounded from below and that M 0 satisfies a Sobolev inequality of dimension ν>3. Let M be a complete Riemannian manifold isometric at infinity to M 0 and let p(ν/(ν-1),ν). The boundedness of the Riesz transform of L p (M 0 ) then implies the boundedness of the Riesz transform of L p (M)
